why are their personal names (ex. "Emily) under my airport?

Hello, I am new to Airport. I have a Q. I bought my imac (leopard) new from the apple store in a sealed box new. when i click on the airport symbol, a small box appears with a list of, i'm guessing connections. The list has only 3 names, none of which i understand. The first is "Emily" - don't know anyone named emily?!? The second is 2WIRE227 - don't know what that is. The third is some long combo of letters & #'s.
I JUST wanted to make sure I don't have a security issue here, or that maybe my neighbors are getting listed??!?
I am about to purchase 2 ipod touches for my daughters for christmas, and i know i'll be using airport or blutooth to connect them to our computer so they can use the internet- otherwise i would have just left Airport OFF.
can anyone tell me if these names are suppose to be there? or what?
THANK you!

Hi, this is just a list of available wireless networks that your Airport has found within range.
If you have yours set up it will be selectable from the list, and with the security key you provide only you or people you allow will be able to connect.
The others should also be secure in some way.

Probably means they are connected tot your wireless network. Do you have it password protected?

so, tkim, if i turn airport off, no one is using my network?
also, the names have a lock next to them.
i do not have a router. i get internet into my house thru dsl modem, for just 1 computer.
from this, do you think there someone else using my connection or is getting into my computer??

or maybe these names are my neighbors and their wifi??

Correct, those are the wireless routers of neighboring households. The little lock next to the name means they are using wireless security. If you are using DSL and an ethernet cable for connectivity, you machine will be very secure.
